Research And Implementation Of Entrance Guard Management System Based On Windows Azure

Currently, efficient and secure network access control system has become a trend. Withthe continuous expansion of cloud computing technology applications, the combination withaccess control systems and cloud computing will no longer be just an imagination. As abusiness model of cloud computing, PaaS can provide server platform services for softwaredevelopment. The proposed scheme that achieves access control system B/S structure-basedPaaS service model can improve software development efficiency, cost savings andoptimization services. Use Microsoft’s Windows Azure platform as a PaaS platform. The maincontents are as follows:(1) Construction of access control system architecture with MVC framework based onthree-tier architecture model. The traditional three-tier concerns overall system architecturelayer, while MVC more concerned about the level of the logic associated with the hierarchicaldisplay. Therefore, in this article, introduce MVC framework model based on the traditionalthree-tier architecture and build a three-tier architecture based on the MVC pattern application,which has advantages of the both: reducing coupling, clear structure and strict separation ofbusiness processing and display, easy to reuse and maintain.(2) Design of the data storage for access management system, including data table designin SQL Database and data storage design in Storage Service. SQL Database has a powerfulsearch, aggregation as the same with the traditional SQL Service database that used to storerelational data tables about access control, user, internal table associated relationalmanagement systems. Storage Service has powerful storage capacity that used store largeamounts of binary data about access pictures, sounds, and other versions of files.(3) Design, implementation of the modules for the access management system based oncloud computing and the WCF Data Communications Services. The access control systemfeatures include: user management, access control basic parameter settings, SIM cardmanagement, IP management, access control state management, Blob file management, access control card records, log management, etc. WCF service is responsible for datacommunication. It provides services including: access control initialization, regular reporting,report, synchronous card and software upgrades. These services use the service contractdefinition and the information structure of data transfer is defined by the contract and messagecontracts.(4) Achieve access control systems under the PaaS mode, and provide system securitydeployment plan according PaaS safety design. Access control system can be deployed to thecloud only after registration Azure account, the process includes creating API credentials,storage services, SQL database services and cloud services. During the period, make theconfiguration according PaaS safety design, to ensure the safety and flexibility of theapplication.
